8502CPU speed / SuperCPU speed detection

[MIRKOSOFT]

Hi!

In my new version of C128 System Information 7.3 revision 1 is one problem with detection of speed of SCPU/8502

/8502 correct peek(53296)-251) = MHz

/65816 at 1MHz peek(53424)=65 / 20MHz peek(53424)=1 > correct

/65816 if 8502=2MHz >incorrect - always 20MHz: peek(53424)=1

Exists other address than 53424 where to check SCPU Turbo on/off?

I know this:

poke53370,0 to slow down 1mhz

poke53371,0 to speed up 20mhz

but peek is always 255

If can anybody help, please write.

Many many thanks!
